E Bike Rear Light

A bike light is a device that is attached to a bicycle to provide illumination for the rider during low-light conditions or at night. It helps increase visibility and safety on the road by making the cyclist more visible to other vehicles and pedestrians.

Bike lights typically consist of a front light and a rear light. The front light is usually white and mounted on the handlebars or the front fork of the bike, while the rear light is red and attached to the seat post or the back of the bike frame. Some bike lights also have additional features such as flashing modes or the ability to adjust the brightness level.

Bike lights can be powered by batteries, rechargeable batteries, or by being connected to a dynamo hub that generates electricity as the bike is pedaled. The choice of power source depends on the cyclist's preference and the intended use of the bike light.

In many countries, it is a legal requirement to have a bike light when cycling in low-light conditions or at night. It is important to choose a bike light that meets the necessary safety standards and provides sufficient brightness to ensure visibility on the road.
